An email to all staff said that Rupert Murdoch, boss of parent company News Corporation, would \"be staying in London to oversee the launch\". Mr Murdoch flew in to the UK last week, and told Sun staff that a Sunday edition would be launched \"very soon\". News International shut down its Sunday paper, the News of the World, last year amid the scandal over phone hacking. The internal memo from News International chief executive Tom Mockridge said: \"As you know, News Corporation has made clear its determination to sort out what has gone wrong in the past and we are fundamentally changing how we operate as a business. \"The commitment of News Corporation to invest in a new edition is the strongest possible message of support we could wish for.\" He went on: \"This is our moment. I am sure every one of us will seize the opportunity to pull together and deliver a great new dawn for The Sun this Sunday.\"
